CGM's - Continuous Glucose Monitors PDF Print E-mail

A continuous blood glucose monitor (CGM) determines blood glucose levels on a continuous basis (every few minutes). A typical system consists of:

  • a disposable glucose sensor placed just under the skin, which is worn for a number of days until replacement (5+ days depending on brand) 
  • a transmitter which communicates to a receiver, placed on top of the sensor
  • a receiver that displays blood glucose levels with nearly continuous updates, as well as monitors rising and falling trends, this can be intergrated in the pump or a separate device. 

Continuous blood glucose monitors measure the glucose level of interstitial fluid.

It does NOT replace the finger pricks but it can help reduce them.  

Start up costs are expensive, but cheaper if you have a compatible pump, Veo or 640G for the Enlite sensors or the Animas Vibe for the Dexcom.  Without a compatible pump you have to also purchase a receiver.  Ongoing costs are sensors.  (replacement transmitters and receivers after warranty runs out) 

There are varios different systems on the market, below shows what is available in the UK.
